one, president obama on a plane with george w. bush and laura bush. president obama will be speaking right before the president of brazil with whom there's been, i would say, frosty relations given the fact we've been tapping her cell phone. >> he may know what she's going to say. >> very good. president castro will be speaking. into this mix we throw ted cruz. given all of that, i wanted to get your thoughts on president obama spoke the day nelson mandela passed away. from your experience with him as a candidate and through the beginning of his presidency, mandela was a larger than life figure for all of us but especially for this president there's a resonance there i'd love to get your thoughts on. >> i'm reminded -- when i heard the news i was reminded in august 2006, i had the opportunity on a trip through africa with then senator obama. we spent half a day on robben island where nelson mandela spent 18 years of his life in a cell. i remember walking into that cell. i remember walking around the grounds. i remember going to the limestone quarries
